• Radio Role Flexibility, allowing for either manual configuration or for the APs to intelligently

determine the operating role of the integrated radios based on the available RF environment. The

AP can operate in the following modes:

2.4GHz and 5GHz role, where one radio serves clients in 2.4GHz mode, while the other serves

–

clients in 5GHz mode.

Dual 5GHz role, with both radios operating in the 5GHz band, actively serving client devices

–

to maximize the benefits of 802.11ac wave 2 and to increase client device capacity.

Wireless Security Monitoring and 5GHz role, where one radio serves 5GHz clients, while the

–

other radio scans both 2.4GHz and 5GHz for wIPS attackers, CleanAir interferers, and rogue

devices.

• Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real

time about RF conditions so that users connect with optimized signal quality and performance.

• Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage

range that offers the fastest data rate available.

• Cisco ClientLink 3.0 technology for improved downlink performance to all mobile devices,

including one-, two-, and three-spatial-stream devices up to 802.11ac Wave 1 and Wave 2. The

technology also improves battery life on mobile devices.

• Cisco CleanAir technology enhanced with 160MHz channel support. CleanAir delivers proactive,

high-speed spectrum intelligence across 20-, 40-, and 80-, and 160-MHz-wide channels to combat

performance problems arising from wireless interference.

• MIMO equalization capabilities, which optimize uplink performance and reliability by reducing

the impact of signal fade.
